Problems solved by technology

[0002] During the manufacturing process of the fuse (fuse) in the fuse, the wire threading, wire cutting and wire bending processes are closely related to the characteristics of the fuse. The cut fuse has burrs, the width of the fuse is very large, and the rated breaking capacity of the product is often relatively low, which will directly affect the characteristics of the fuse

Embodiment 1

[0047] see figure 1 As shown, the invention discloses a cable-stayed automatic wire threading and cutting machine, including an automatic threading device, a wire cutting device, and a cable-stayed wire bending device. Among them, if the wire bending function is not required, only the automatic wire threading device and the wire cutting device can also be used to achieve the functions of automatic wire threading and cable-stayed wire threading.

[0048] Please combine Figure 1 to Figure 7 As shown, the automatic wire threading device includes a fuse reel 10 that automatically conveys the fuse, a guide threading wheel 2301 that receives the fuse conveyed from the fuse reel, and a fixed threading wheel that cooperates with the guide threading wheel 2302, movable threading wheel 2303 coordinated with the fixed threading wheel, wire guide nozzle 34 located at the outlet of the fixed threading wheel and the movable threading wheel; the movable threading wheel approaches or moves ...

Embodiment 2

[0054] The technical scheme of the method for assembling the fuse using the cable-stayed automatic wire threading and wire cutting machine of Embodiment 1 is:

[0055] The fuse 19 in the fuse reel 10 passes between the fixed threading wheel 2302 and the movable threading wheel 2303 through the transition of the guiding threading wheel 2301, and along with the movement of the fixed threading wheel 2302 and the movable threading wheel 2303 Rotate, the fuse 19 passes downwards, passes through the insulating tube 44 through the wire guide nozzle 34;

[0056] After the fuse 19 passes through the insulating tube, the fuse cutter 40 moves toward the fuse and cuts the fuse 19, and the upper part of the cut fuse 19 abuts against the beveled front end face of the cutter to make the fuse In the insulating tube, it extends in a diagonal direction of the inner cavity of the insulating tube.

Embodiment 3

[0058] Embodiment 3 is also a method of using the cable-stayed automatic wire threading and wire cutting machine of Embodiment 1 to assemble a fuse. In Embodiment 3, the wire bending function provided by the cable-stayed wire bending device is added.

[0059] The specific technical solutions are:

[0060] The fuse 19 in the fuse reel 10 passes between the fixed threading wheel 2302 and the movable threading wheel 2303 through the transition of the guiding threading wheel 2301, and along with the movement of the fixed threading wheel 2302 and the movable threading wheel 2303 Rotate, the fuse 19 passes downwards, passes through the insulating tube 44 through the wire guide nozzle 34;

[0061] Move the lower bending platform 461 of the fuse so that the perforation 47 of the lower bending platform is located below the insulating tube. The wire moves and cuts the fuse 19, and the upper part of the cut fuse 19 abuts against the beveled front end face of the cutter so that the fuse ...

Abstract

The invention discloses an inclined-pulling type automatic threading and cutting machine. According to the machine, threading is controlled through a stepping motor, so that the stability of threadingis improved; an arc-shaped metal strip is used as a fuse wire of the fuse, and the flat fuse wire is formed into an arc-shaped fuse wire by adopting a pressing wheel concave-convex mold pressing method, so that the width of the fuse wire is reduced, the possibility of direct insertion threading is achieved, and the characteristics of the fuse wire are improved; a fuse cutter is made of wear-resistant tungsten steel, wire cutting is clean, burrs are avoided, and meanwhile the fuse cutter is controlled by an air cylinder, so that the stability of wire cutting is greatly improved; and the inclined pulling type threading design is adopted, the threading mode that concave-convex wheel presses the flat fuse wire, so that the flat fuse wire is formed into the arc-shaped fuse wire is adopted, andis different from a traditional flat fuse wire straight insertion threading mode, and then the feasibility of improving the breaking capacity of a product by adopting a filling and arc-extinguishingprocess can be realized.

Description

technical field [0001] The invention relates to a fuse for large current application, in particular to a structure of a high rated current and small-sized surface-mounted fuse, and a mass production method of the fuse. Background technique [0002] During the manufacturing process of the fuse (fuse) in the fuse, the wire threading, wire cutting and wire bending processes are closely related to the characteristics of the fuse. The stability of the threading, the fuse sticking to the inner wall of the ceramic tube, the cutting wire is not clean The cut fuse has burrs, the width of the fuse is very large, and the rated breaking capacity of the product is often relatively low, which will directly affect the characteristics of the fuse. [0003] To sum up, a new technical solution is needed to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a cable-pull type automatic wire threading and cutting machine, which can f...
